Similar numerals refer to similar parts throughout the drawings.

The wagon-box 1 rests on theordinary bolsters 2 etween the standards 3 of an ordinary W`a on-gear, and the longitudinal bot tom boar s 4 on the cross-sills 5 ar'e preferably located with a slight interval between them to provide for lateral expansion. The side-boards 6 are preferably stayed on the outside by the braces 7, attached on the outer projecting ends oi the cross-sills. The side-boards extend a short distance to the rear beyond the ends of the bottom boards, and on these projecting ends are attached the main bearings 8 for the transversely-located `main shaft 9 of the machine.

v4The rake-frame is pivotally mounted concentric with vthe main shaft, preferably by means of the bearing-brackets 10, journaledf on the hubs 11 of the main bearings, andthe bearing-collars 12 are provided on the. shaft and preferably shield the ends of the abutting bearings from dirt or it. The rake-frame is preferably com ose of the side bars 13, attached to the caring-brackets, the forward, middle, and rear cross-bars 14, 14, and 14h., the intermediate cross-bars 14 and 14d, the cross-tie rod 15 and 15.8L at the.forward end and middle, the diagonal brace-rods 16, from the middle to the rear end, and the longitudinal bearing-strips 13, attached at intervals a art on the under sides of the crossbars. T e side bars and the bearin rips are preferably tapered in width, so, t a the IOOl l ed at intervals apart on the main shaft, and the fre end of the frame lighter than the base` en Themain sprockets 17 are 'securely mountcorresponding idle sprockets 19 are mounted in suitable bearings formed in the brackets 20, attached to the forWaI'd\cross-bar of the frame, and the sprocket-chains 21 operateon bl wilf'not overlap, but will bring the lines of Ione chain will be opposite the intervals be tween therakes of the 'adjacent-chain, and the sprocket-wheels and chains are preferso separated that the ends of the rakes travel of the adjacent end tangs somewhat closer together than are the .tangs of the respectiverakes. The chains are also alined with thebearing-strips, sothat these strips constitute a stay or support against which.

the -chains and fakes abut in the operation of the machine'.

The Shield or hood 25 is attached on the' free end of the rake-frame to protect the driver from being caught by the sprocketwheels and rakes and to keep the idle K sprockets clean, andthe feet 26 are provided at this end to hold the frame up, so that the are preferably of about the same/ diameter as rakes will not rest or drag too much on the bottom boards of the box. The cylindric shieldsor drums 27 are provided around 'the' main shaft between the sprocket-Wheels and the rims of the`wheels, which prevent straw or other refuse .from engaging or wrapping laround the rotatable parts, and the brushes 2 8 are attached ontheadjustable transverse bar 29,. back ofthe main sprocket-wheels and ser-ve to remove adheringmaterial from the Wheels and chains.

. The crank-shaft 30 is mounted in the bearings 31 and 31 at the rear end of the box, referably horizontaland to the rear and beow,'the main shaft. The cog-pinions 32 are securely lmountedon this shaft, preferably insideof and adjacent tothe side boards, and the crank 33w1th the' handle 34, is securely y f-mounted on the projecting end of this shaft,

.preferablyon-the right side .of the wagon-box The cog"- sectors 35 are formed or attached4 on the rear ends of the bearing-brackets 10 and are adapted to mesh with the cog-pinions on the crankfshaft, so that by rotating' the crank the yforward end of the rake-frame is raised or lowered, being rocked on its y ivotal bearings by means of the intermes 'ng cog pinions and sectors.' l The ratchet-wheel -36 is securely mounted on the crank-shaft,

preferably between the crank and the adjasessel cent bearing, and yone half or side of its periphery is provided with the ordinary inclined l faced or acute-angled teeth 37, while the other half or side is provided with the squareshouldered'recesses 38. Y The pawl 39 is pivotally attached, preferably on the late 40 of the bearing 31, and one'side o the pawl is provided with the acute-angled vdetent 41, which is adapted to engage with the acute-l angled teeth -of the ratchet, -While the other side of the pawl isprovided with the square detent 42, which is adapted to engage in the square-shouldered recesses of the ratchet, ac-

cording as the pawl is thrown one way or'the other. The flat-facedlugs 43, having inclined sides 44, are provided on the end of the pawl-hub 45, against which-v the ends of the bow-spring 46, securely attached on the pawl bearing 47, are adapted to operate, by means of which the pawl is releasably held in a vertical position out of engagement with the ratchet-wheel, when the rake-frame is being raised. The crank-handle is loosely mounted on its shaft and is free lto move endwise thereon between the hub 48 of theratchetwheel and the stop-pin 49, and the contiguous ends of the crank and ratchet-hubs are provided with the engaging inclined-'faced square-shouldered'teeth 5() arranged Vto freeA the crank from rotationwhen the rake-frame 95 the operation ofthe mais being lowered in chine. f

' The wheel-sprocket 51 is. attached, ably, on the inside to the left rear whee of the wagon, and a convenient way of making this roo` attachment is by the bolts 52, passed through the slots. 53 inthe web 54 of the wheelsprocket and having their free ends 5 5 curved or crooked to engage around the spokes 56 of the wheel with the intervening 105 notched washer57. The clutch-sprocket 58- is rotatably mounted on the projecting endof the vmain `shaft in alinement with the wheel-sprocket and is preferably held in pol sition by 'means of the adjusting-collar 59, no

clam ed on the shaft on the-outer side ofthe sproc et, which collar is provided with the. internal annular flange l60, .adapted to engage and operate in 'the external annular groove 61,formed,in the hub of the sprocket, 11 5.

y means of which collarpthe sprocket can be readily adjusted' endwise along the shaft to bring itv into alinement with the wheelsprocket. The clutch-collar 62 is feathered on the shaftinside theclutch-sprocket, and rizo the, contiguous ends of the collar and' sprocketl are provided with the engaging squareshouldered inclined-facedteeth 63. The feather 64 is attached in the groove 65 in the `clutch-collar by the keyv 66,'passed-rz5 through the apertures 67 1n t-he lugs 68 out.

arrangement is necessary to permit the 13oreferv u IO l' shaft.

clutch-sprocket to be adjusted along the backward. The operating sprocket-chain 95 shaft for use in wagons of different widths. is provided for the `wheel and clutch sprockets, by means of which power is transmitted The minor bearing 7 1 for the main shaft is attached on the outer side of the left side-board, preferablyby the plate 72 and the bolts 73, and the clutch-bracket 74 is preferably attached by means of its plate 75, abutting against the bearing-plate and secured by the same bolts. The outer bearing 76 is formed on the clutch-bracket, by means ofwhich minor and outer-bearin s the projectin end of the main shaft is firm y supported an sustained, and it is evident that the arts of the clutch can be readil removed or cleaning' and repairs by merely removing the clutchbracket and without disturbing the main The flange 77 is Aminor bearing adjacent to its plate, and the clutch-bolt 78 is arranged to o erate endwise in suitable apertures 7/9 in t e flange and plate. The coil-spring'SO is provided around Vthe bolt between the'be'arin -plate and the.

stop or pin 81 on the bolt, w 'ch spring acts to throw the bolt endwise outward, and on the free outer end of the bolt is provided the adjustable yoke 82, whichis adapted to operate in the annular groove 83 of the clutch-cob,

lar, whereby the sprin acts to hold the collar in engagement wit the clutch-s rocket.

The inner end of the clutch-bolt is ent upward to form the shoulder 84, which is ada ted to o erate in the recess 85 in the si cboard o the box, and the longitudinal channol 86 is provided in the side-board and extends from this recess to the forward end of the side-board, in which recessthe operat' bar 87 is located and is adapted to move diiwise without interferin with or' being restrained by thebolstere standards.

The operating-lever 88 is pivoted to the forward end of the side-board and is provided with the slot 89, in which the wristin 90 on the forward end of the operating-bar is adapted to operate.

the inside to'form the wedge-face 92, andin the rear end of this face is provided the notch 93. The channel 94 is provided in the side-board to accommodate the movement of the wedge end of the operating-bar.

`-The shoulder 84 on the inner end of the clutch-bolt is kheld by action of the spiral spring against the innerside of the operating-bar when the clutch-collar and sprocket` are inA enga ement, and when it is desired to throw the c utch out ofenga ement the oprovided lon the The rearf` part 91 of the operating-bar is thickened on from the wagon-wheel tothe unloading mechanisin. i j q When the wagon is empty, the clutch is thrown out of engagement and the feet at the 4free end of the rake-frame normally reston vthe bottom of the box, as shown by broken `lines in Fig. 1, and when it is desired to load the wagon the pawl is .thrown u out of eny rotationv gagement with the ratchet, and of the crank the frame is raised to or near the vertical position, as shown by dotted lines in Fig. 1, whereupon the square detent of the pawlfis thrown into Aa square-shouldered recess of the ratchet-wheel, which prelvents a movement of the rake-frame either forward or backward, in which position the load 96 may be placedv on the wagon without any danger of the frame falling either way by Ireason of a sudden movement thereof. When thewagon is loaded, the pawl is thrown so lthat its acute-angled detent is in engagement with the acute-angled teeth of the ratchetwheel, and the rake-frame is lowered by means .of the crank until it rests against the rear end, of the load, as shown by full lines in 1. In this relation the pawl permits the frame to be freely lowered, but prevents a reversemovement of the same, and thus saves `the frame from being thrown backward by a' sudden forward movement of the wagon.

`.The. wa on is now hauled from the barnyard to ithe eld, .and when vthe place of distribution is'reached the clutch is thrown into engagement, and by the operation of the machine the rakes are drawn downward and lref irwardbetween the manure and the bearing-strips, and comb and cut through and '.pulverize the manure and carry the particles thereof to the rear end of the wagon, from which they are discharged and distributed in an even manner through the throat between the shaft-shield and the adjacent rear ends of the bottom boards. The width of this throat is` regulated bythe adjustable extension 97,

attached on the 'rear ends of the bottom IOO IOS

boards of the box. The weight of the frame b y the bearing of its strips against the inner sides of theVlsprocket-chains im resses the rakesin engaging contact with t e manure,

and as the load is reduced the rake-frame which are apt to pack in bulk. The wheel- ISO ment of these stops the operating sprocketchain can be kept taut without other tightening devices. l

t is evident that the unloading mechanism herein illustrated and described can perform its work with the application of very little power, because the load is removed by raking -or scraping small portions from the top there-` of. Furthermore, as the load does not rest.

upon any part of the mechanism there is no limit to the weight or quantity of the load which can be removed by the mechanism excepting only the strength and capacity of the wagon and its box.
